Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

If you haven't already done so, run the SQL script in the above folder to generate the Make-a-Mammal database.

Create a new Power BI Desktop file, and load the tables from this database into your model. 

Create measures so that you can display this table:

Missing out environments

The last 3 columnns omit (respectively) the air, land and water figures.

 

You'll need to create 3 measures, each one combining the CALCULATE and VALUES functions to omit one particular environment value.

Too easy? Combine the SUMX and FILTER functions to show the following table:

Expensive and cheap

The last two columns come from measures summing the sales quantity (but instead of doing it over the entire purchases table, they just do it over those purchases which cost at least 10 pounds or less than 10 pounds, respectively).

 

Save your file as DAX fun, then close down the instance of Power BI Desktop that you're using.
